Abstract: A solid-state imaging device includes: a plurality of pixel circuits arranged in rows and columns; a plurality of unit power supply circuits that generate a second power supply voltage from a first power supply voltage based on a reference voltage and supply the second power supply voltage to amplifier transistors provided in the plurality of pixel circuits; and a regulator circuit that generates the reference voltage that is constant. Each of the unit power supply circuits is provided for a corresponding one of the columns of the plurality of pixel circuits or for a corresponding one of the pixel circuits, and supplies the second power supply voltage to the amplifier transistors in the pixel circuits that belong to the corresponding one of the columns or to the amplifier transistor in the corresponding one of the pixel circuits.

Abstract: A solid-state imaging device includes: a pixel array including a plurality of pixel circuits arranged in rows and columns; a vertical signal line that is provided for each of the columns and transmits pixel signals; a column AD circuit that is provided for each of the columns and AD converts the pixel signals from the vertical signal line; a column-switching circuit that is interposed in the vertical signal line between the pixel array and the column AD circuit and switches connection between the vertical signal line and the column AD circuit; a controller that causes the column-switching circuit to switch the connection for every horizontal scan period; and a restoration circuit that restores ordering of the AD converted signals so as to correspond to ordering in which the vertical signal lines are arranged in the pixel array.
